You may think that with a price-to-sales (or "P/S") ratio of 1.2x Sunrun Inc. (NASDAQ:RUN) is a stock worth checking out, seeing as almost half of all the Electrical companies in the United States have P/S ratios greater than 1.8x and even P/S higher than 5x aren't out of the ordinary. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

How Sunrun Has Been Performing

While the industry has experienced revenue growth lately, Sunrun's revenue has gone into reverse gear, which is not great. The P/S ratio is probably low because investors think this poor revenue performance isn't going to get any better. So while you could say the stock is cheap, investors will be looking for improvement before they see it as good value.

Is There Any Revenue Growth Forecasted For Sunrun?

Sunrun's P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 2.7%. Still, the latest three year period has seen an excellent 145% overall rise in revenue, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would definitely welcome the medium-term rates of revenue growth.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 10% each year over the next three years. That's shaping up to be materially lower than the 33% per annum growth forecast for the broader industry.

With this in consideration, its clear as to why Sunrun's P/S is falling short industry peers. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

The Final Word

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

As we suspected, our examination of Sunrun's analyst forecasts revealed that its inferior revenue outlook is contributing to its low P/S. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
